Recommendation: Salesforce (CRM + Field Service) for mid-market organisations (budget range $50,000–$1,000,000) where both platforms support GDPR natively. SAP S/4HANA suits larger organisations with budget from $500,000 and more complex compliance requirements.
The criteria that determine this recommendation — GDPR module coverage, integration approach, budget range, and deployment model — are set out in the comparison table below.

Where they differ on GDPR
GDPR module coverage
Salesforce (CRM + Field Service): ✓ Native. Compliance modules listed: HIPAA, GDPR. SAP S/4HANA: ✓ Native. Compliance modules listed: SOX, HIPAA, GDPR, ASC 606.
The practical difference: a platform with a native GDPR module includes consent tracking, DSAR workflow scaffolding, and ROPA fields out of the box. A platform without one requires integration with a dedicated privacy platform (OneTrust, TrustArc, DataGrail) for each of these functions. That integration layer adds cost, adds failure points, and adds audit complexity — the external tool must be recognised as a sub-processor and documented accordingly.
Integration approach
Salesforce (CRM + Field Service) integrates via: MuleSoft; REST APIs; pre-built ERP connectors (SAP, NetSuite, Dynamics)
SAP S/4HANA integrates via: SAP Integration Suite (iFlow); pre-built connectors for Salesforce/Workday; REST/OData APIs
For GDPR specifically, the integration question is: can consent withdrawal in the CMP propagate to this platform in real time? Both platforms expose APIs that can receive a withdrawal event, but the mechanism differs. Salesforce (CRM + Field Service)'s MuleSoft is well-documented for consent propagation.
Deployment and data residency
Salesforce (CRM + Field Service) deploys as: Cloud (SaaS) SAP S/4HANA deploys as: Cloud (RISE), On-premise, Hybrid
Both platforms offer cloud deployment with EU data residency options. Verify your tenant is configured for EU data residency before go-live — this is a provisioning-time decision, not a setting that can be changed post-implementation without data migration.
Known limitations relevant to GDPR
Salesforce (CRM + Field Service): Not a financial ERP (requires integration for AP/AR/GL); high per-user cost at scale
SAP S/4HANA: High TCO; long implementation; requires dedicated SAP BASIS team; heavy customisation lock-in
Strengths relevant to GDPR
Salesforce (CRM + Field Service): Market-leading CRM; Field Service Lightning strong for scheduling; AppExchange ecosystem
SAP S/4HANA: Deep manufacturing and supply chain; mature compliance tooling; global multi-entity support

Frequently asked questions
No platform passes or fails a GDPR audit on its own. The audit assesses the organisation's compliance — the platform is one component. What matters is whether the platform is configured correctly, integrated with consent and DSAR tooling, and documented in the ROPA with the correct lawful basis per data category.
